You use Assembly constraints to restrict translation/rotation. You can then use the compass (holding Ctrl-key down to respect the constraints), or the "Manipulation" function (tick the box) to move the parts according to the free DoF...
In the past i have created this. For when we don't have DMU kinematics at disposal, we need to make some workarounds. I wanted to make sure all tooling kinematics worked as I planned, so I needed to think out of the box.
I can make some general explanation of the work flow.
Create a new Product, where you will put all of your assemblies. Lower part is rigid, lifter, pad, upper tool, one product each, and if you have any other components with other kinematics, than you need another assemblies.
First you need to have the curve of press's kinematics. Remember that the press will be the "motor" of your kinematics. So for a defined press angle, you will have an height for the upper part of tool.
In this case, your press angle is 132º, and the height is 64.529 mm.
So you have your first constraint. You will constraint the upper part, with lower, with an offset constraint, where you will link the distance to the sketch offset distance. Now if you change the angle, your height will update accordingly.
For the lifter same thing. in this case, you will need to cut the curve, according to your lifter stroke.
Some thing for blank holder, and others...
To create the animation, I have created a macro, that will export an image for each press position (each 5 degrees, or 10 degrees), then with an image, there are a few softwares that can convert images in videos.
While drawing it's not that versatile to do the videos. But very usefull to change the press angle, and understand what's going on with your kinematics. Specially if you have any cams.
